nuptial (adj.)

late 15c., from Middle French nuptial, or directly from Latin nuptialis "pertaining to marriage," from nuptiae "wedding," from nupta, fem. past participle of nubere "to marry, get married, wed, take as a husband," which is of uncertain origin. Perhaps from PIE *sneubh- "to marry, wed" (source also of Old Church Slavonic snubiti "to love, woo," Czech snoubiti "to seek in marriage," Slovak zasnubit "to betroth"). Related: Nuptially.
